Dreempipes is the third level of the episode The Chase Is On from Jazz Jackrabbit.
This is the fuel refinery for Devan's destroyers! The entire planet is covered with purple goo and Jazz must swim through it in order to destroy Devan's handiwork. Shoot the switches to raise and lower the water level!
Dreempipes is the first stage in the game to feature underwater sections. In order to navigate the level, you have to dive into the water, all while dealing with the floating Mines on the way, then find and hit red switches on the walls which will rise the water level, allowing Jazz to proceed further. At various points you have to enter the large pipes, which will take you to another portion of the stage.
Though you can find Hip Hops in this stage, they are unable to dive underwater alongside Jazz.
